Description

CAP VACUUM PUMP OF COSMETIC VESSEL}

The present invention relates to a cap pump structure of a cosmetic container, and more particularly, to a cap pump structure of a cosmetic container configured to discharge a predetermined amount of high viscosity contents filled in the cosmetic container.

In general, cosmetics such as liquid foundation composed of a liquid is used in a cosmetic container installed with a cap pump to ease the use by a certain amount.

That is, after the cap pump is coupled to the cosmetic container, the contents are discharged by a predetermined amount each time it is pressed once, so that the liquid cosmetics are used comfortably.

The cosmetic container and the cap pump is coupled to the container 51 is filled with the contents, such as liquid foundation, as shown in Figure 5 and the cap pump coupling inlet 50 is formed on the top, and Lifting body 52 which is coupled to the inside of the container 51 can be lifted and the cap pump 53 is coupled to the inlet 50 is configured to suck and discharge the contents every time the pumping.

Since the cap pump 53 sucks and discharges the contents and air inside the container 51 and does not allow external air to flow therein, the lifting body 52 rises with the discharge of the contents. It always pumps out the contents while creating a certain space.

Here, the material of the general cap pump 53 used in the cosmetic container 51 is to use PE (polyethylene).

However, when the liquid cosmetics such as liquid foundation and the like are used in the cosmetic container combined with the cap pump as described above, since the contents are very high in viscosity, the cap pump is not buried and the pumping action is not performed well. When the pump is pressed without a return operation is not well made.

That is, the above-mentioned high viscosity contents are stuck to the inside of the cap pump, in particular, the valve, thereby preventing the valve from being opened and closed, resulting in poor valve operation and poor return operation of the cap pump.

In addition, the components (PE) constituting the cap pump is expanded due to the moisture of the cosmetics (cosmetic with high viscosity) to increase the friction force in each movement, opening and closing action, thereby causing a malfunction of the cap pump There is a problem.

Therefore, an object of the present invention is to solve the above problems, even when using a high-viscosity cosmetics in a container to prevent the occurrence of malfunction due to the contents buried in the valve and in addition to the expansion of the components by the moisture of the contents It is to provide a cap vacuum pump structure of the cosmetic container configured to prevent the operation of the cap pump to be made smoothly.

In order to achieve the above object, the present invention is a cylindrical valve housing made of a material which is formed of a first valve sheet formed with a plurality of through holes in the bottom surface and does not expand in water, and is in close contact with the first valve sheet. It is formed to open and close it, the valve is made of a material that does not expand in water, the first spring is installed to press the valve close to the first valve seat and the second valve seat so that the upper end of the first spring is in close contact Is formed and moves inside the valve housing and serves as a piston, the contents of the cosmetic container is configured to be discharged to the outside, the piston means made of a material that does not expand in water, and the through hole is formed so that a portion of the piston means protrudes to the outside And a housing cap coupled to an upper surface of the valve housing, and the housing cap inserted into and fixed. If the container cap and coupled to cosmetic containers, coupled to a top surface of the piston means pressing them by hand, characterized in that consists of a cap that is configured to push the contents are ejected.

1 and 2 are an exploded perspective view and an assembled sectional view showing a cap vacuum pump structure of a cosmetic container according to the present invention, a cylindrical shape formed with a first valve sheet (2) having a plurality of through holes (1) formed on the bottom The valve housing 3 and the valve 4 formed in close contact with the first valve seat 2 and open and close the valve housing 3, and the valve 4 is pressed against the first valve seat 2. A second valve seat 6 is formed to closely contact the upper end of the first spring 5 and the first spring 5 installed therein, and serves as a piston while moving inside the valve housing 3. Piston means configured to discharge the contents of the outside, a through-hole 7 is formed so that a portion of the piston means protrudes to the outside and the housing cap 8 is coupled to the upper surface of the valve housing 3, The housing cap 8 is inserted into and fixed to the cosmetic container 51. Consists of a container cap (9) and a push-cap 10 is configured in combination with an upper surface of the one piston means to urge it by hand.

The valve 4 is formed such that the lower end of the first spring 5 is in close contact with the valve body 12 having a plurality of communication grooves 11 through which contents can move around the valve body 12, and the valve body 12. It is composed of a ball valve 16 which is coupled to the fitting groove 13 and the fitting protrusion 14 on the bottom surface, and the valve plate 15 is thinly formed to open and close the through hole 1 of the first valve seat 2. have.

In particular, the first valve seat 2 and the ball valve 16 in contact therewith are valve valves of the first valve seat 2 and the ball valve 16 in the direction in which the contents are discharged as shown in FIG. 3. (15) is curved so that the valve plate 15 is more easily separated from the valve seat when the contents are leaked out.

The piston means has a cylindrical piston 18 which is formed at the lower end of the second valve seat 6 and is in close contact with the inner surface of the valve housing 3 to serve as a piston, and the piston 18. ) Is inserted into the second spring (19) and is pressed to protrude to the lower end of the piston 18, the vent hole 20 is formed so that the contents are introduced, the upper end is opened and combined with the pressing cap 10, through the contents It consists of the piston member 21 which discharge | releases.

Of course, the sealing ring 22 is provided between the housing cap 8 and the container cap 9 and between the housing cap 8 and the cosmetic container 51.

In particular, the material of the valve housing 3, the piston 18, the ball valve 16 is made of silicon + MBR (butylene rubber) + VLDPE (ultra high density polyethylene) bar, the mixture of the ultra-high density polyethylene Accordingly, when the respective materials are rubbed with each other, the frictional force is reduced, and the sealing is firmly made, and thus the sliding is easily performed.

In addition, the silicone, butylene rubber, ultra-high density polyethylene and the like have a very small volume expansion ratio due to moisture, and thus prevent the ball valve 16 and the piston 18 from expanding by the contents to prevent the valve action. It will be smooth.

When explaining the operation and effect of the present invention as described above to insert the fitting projection 14 of the ball valve 16 to the fitting hole 13 of the valve body 12 and to insert it into the valve housing (3) Bar, the valve 4 is arranged to be in close contact with the first valve seat (2) to open and close it.

When the first spring 5 is introduced into the valve housing 3 in this state, the first spring 5 is pressed against the upper surface of the valve body 12. Insert the piston 18 so that the second valve seat 6 is in close contact with the upper end of the c), and then insert the second spring 19 and the piston member 21 therein, and attach the housing cap 8 to the upper surface thereof. Will be combined.

Of course, a coupling protrusion (not shown) is formed between the valve housing 3 and the housing cap 8 to maintain the coupling of the valve housing 3 and the housing cap 8.

As described above, when the valve housing 3 and the housing cap 8 are coupled, they are coupled to the container cap 9 again, and the container cap 9 is coupled to the container 51 while the container cap 9 is coupled to the container 51. The pressing cap 10 is coupled to the piston member 21 protruding from the 9).

In this state, the assembly of the cosmetic container is completed, and when the pressing cap 10 is pressed, the piston member 21 connected thereto is pressed while the second spring 19 is compressed and compressed at least. When the piston member 21 is lowered when exposed to the lower portion of the piston 18.

At this time, the vent hole 20 formed in the piston member 21 is opened and the piston 18 is pressed in this state while compressing the first spring 5 and the piston 18 is downward.

When the piston 18 is downward, as the air inside the valve housing 3 is discharged to the outside through the communication hole 11, the piston 18 is circularly downward. In this state, the valve 4 is As shown in FIG. 4A, the first valve sheet 2 is shielded so that the contents do not flow into the valve housing 3.

In this state, when the pressing force of the pressing cap 10 is removed, the pressing cap 10 and the piston 18 are suddenly raised by the force of the first and second springs 5 and 19. At this time, the valve 4 is bent upward as the air inside the valve housing 3 is expanded, and the through hole 1 of the first valve seat 2 is opened as shown in FIG. 4B. Is sucked and filled in the valve housing 3.

In particular, since the first valve seat 2 and the valve 4 are curved in a predetermined curvature, it is easier for the valve 4 to be detached from the first valve seat 2 than in a plane. Thus, the above contents more easily pass through the through hole 1 of the first valve seat (2).

When the contents are filled in the valve housing 3, the valve 4 is closed again. In this state, the piston 18, the valve housing 3, the valve 4, etc. expand due to the moisture of the contents. The initial play is kept constant so that the valve and piston work smoothly.

When the pressing cap 10 is pressed again while the contents are filled in the valve housing 3, the piston member 21 is pressed while first compressing the second spring 19. The contents are discharged to the outside through the vent hole 20 of 21), and the contents are discharged to the outside while repeating the same action.

Here, even if the viscosity of the cosmetic contents is high, the ultra-high density polyethylene is mixed and formed in the materials of the piston 18 and the valve 4 so that the piston 18 is not easily inflated by water, thereby smoothly moving the piston 18. This ensures an easy pumping operation even when discharging high viscosity contents.

As described above, the present invention fills the cosmetic container with high viscosity to the cosmetic container and discharges it to the container pump, so that the components of the pump are not expanded by the moisture of the content and the first valve sheet and the valve are curved. By forming, there exists an advantage that the pumping action of the cosmetic content with high viscosity becomes smooth.
